Genuine AirTAC filter regulator, order code GTFR20006LNK from the GTFR200 range. The options this code selects are decoded below; series data follow the official AirTAC catalog.
GTFR20006LNK pairs two option letters on the low-pressure AirTAC GT200 filter regulator: N, which removes the pressure gauge, and K, which adds a check valve. Regulation stays within the 0.15 - 0.4 MPa (20 - 58 psi) band through 1/8 inch (06) PT ports, with the standard 40 um filter element doing the air cleaning.
The body is the compact GT200 short PC bowl, the tighter derivative of GA200, drained by differential plus manual operation, and a mounting bracket is included since the code omits J. Because no gauge is fitted, downstream setpoints have to be read by an instrument elsewhere in your panel.

GTFR20006LNK differs from GTFR20006LK only in the gauge: both are low-pressure builds with the same check valve, 40 um element and 1/8 inch PT ports, but LNK leaves the body gaugeless. If you want the check valve plus a fitted indicator, order GTFR20006LK; without the check valve, GTFR20006LN is the plain gauge-free sibling.
Branch layouts specified with a check valve in line, served by the K suffix while the regulator holds setpoints in the 0.15 - 0.4 MPa (20 - 58 psi) low band.
Machine lines where a controller reads pressure through its own transmitter, making the N-coded build without a gauge the correct variant to order.
Shallow enclosures fed by 1/8 inch PT air lines, where the short PC bowl body and included mounting bracket keep the installation footprint small.
1/8 inch (06) PT ports, low-pressure regulation 0.15 - 0.4 MPa (20 - 58 psi), 40 um filter element, short PC bowl with differential and manual drain, check valve (K), no gauge (N), mounting bracket included, fluid air.
Both are low-pressure GT200 units with a check valve, bracket, 40 um element and 1/8 inch PT ports; LK carries a fitted pressure gauge while LNK is the N-coded version without one. If panel indication is required, choose LK or plan your own external gauge with LNK.
